Optimal Calibration of Items for Multidimensional Achievement Tests
Peer reviewed Peer reviewed
Direct linkDirect link
Mahmood Ul Hassan; Frank Miller – Journal of Educational Measurement, 2024
Multidimensional achievement tests are recently gaining more importance in educational and psychological measurements. For example, multidimensional diagnostic tests can help students to determine which particular domain of knowledge they need to improve for better performance. To estimate the characteristics of candidate items (calibration) for…

Detecting Multidimensional DIF in Polytomous Items with IRT Methods and Estimation Approaches
Peer reviewed Peer reviewed
Direct linkDirect link
Güler Yavuz Temel – Journal of Educational Measurement, 2024
The purpose of this study was to investigate multidimensional DIF with a simple and nonsimple structure in the context of multidimensional Graded Response Model (MGRM). This study examined and compared the performance of the IRT-LR and Wald test using MML-EM and MHRM estimation approaches with different test factors and test structures in…

Multidimensional Classification of Examinees Using the Mixture Random Weights Linear Logistic Test Model
Peer reviewed Peer reviewed
Direct linkDirect link
Choi, In-Hee; Wilson, Mark – Educational and Psychological Measurement, 2015
An essential feature of the linear logistic test model (LLTM) is that item difficulties are explained using item design properties. By taking advantage of this explanatory aspect of the LLTM, in a mixture extension of the LLTM, the meaning of latent classes is specified by how item properties affect item difficulties within each class. To improve…

Unidimensional Interpretations for Multidimensional Test Items
Peer reviewed Peer reviewed
Direct linkDirect link
Kahraman, Nilufer – Journal of Educational Measurement, 2013
This article considers potential problems that can arise in estimating a unidimensional item response theory (IRT) model when some test items are multidimensional (i.e., show a complex factorial structure). More specifically, this study examines (1) the consequences of model misfit on IRT item parameter estimates due to unintended minor item-level…

A Multilevel Nonlinear Profile Analysis Model for Dichotomous Data
Peer reviewed Peer reviewed
Direct linkDirect link
Culpepper, Steven Andrew – Multivariate Behavioral Research, 2009
This study linked nonlinear profile analysis (NPA) of dichotomous responses with an existing family of item response theory models and generalized latent variable models (GLVM). The NPA method offers several benefits over previous internal profile analysis methods: (a) NPA is estimated with maximum likelihood in a GLVM framework rather than…

Examining Sources of Gender DIF in Mathematics Assessments Using a Confirmatory Multidimensional Model Approach
Peer reviewed Peer reviewed
Direct linkDirect link
Mendes-Barnett, Sharon; Ercikan, Kadriye – Applied Measurement in Education, 2006
This study contributes to understanding sources of gender differential item functioning (DIF) on mathematics tests. This study focused on identifying sources of DIF and differential bundle functioning for boys and girls on the British Columbia Principles of Mathematics Exam (Grade 12) using a confirmatory SIBTEST approach based on a…
